Advancements in The Screen Technologies Of Apple IPhones

Upgrades in display technology :
Starting from ordinary LCD screens in the early days to the OLED screens used in the iphone X and consequent models. The screens of iphone have significantly improved in terms of color performance, contrast ratio, and brightness. OLED screens have each pixel emitting light independently. Eliminating the need for backlight components. This makes screens thinner, enables higher contrast ratios and more accurate color reproduction. At the same time, it also supports wide color gamut and high dynamic range(DHR) ,making the display effects of photos and videos more vivid and lifelike.

Enhanced resolution:
With the development of the technology. The resolution of apple iphones screen has been continuously improved. It has gradually increased from the lower resolutions in the early days to the current high-definition or even ultra-high-definition resolutions. For example, the 6.1-inch screen of the iPhone 15 Pro has a resolution of 2556×1179 pixels and a pixel density of 460 ppi, which can provide a clearer and more delicate display effect for images and texts, meeting users' needs for a high-definition visual experience.

Optimized design：
The screen design of Apple iphone has been also continuously innovated. From the traditional rectangular screen to the screen with round corner and full screen design. The screen-to-body ratio has gradually increased. For example, the iphone X series introduced 'Dynamic Island ' design. Not only does it achieve a higher screen-to-body ratio, but also through the combination of software and hardware, the area of the front-facing camera and sensors has been ingeniously designed, making it an interactive area that enhances the user experience.

Improved Durability：
Apple has been constantly committed to improving the durability of the screen. For example, it uses ceramic shield, which has been specially treated to have high hardness and anti-drop performance, effectively reducing the risk of damage to the screen caused by accident collision or drops during daily use.

In addition. The latest patents show that Apple is researching and developing multi-layer glass composite structure, which further enhance the screen's scratch resistance and outdoor visibility.
